Snapcraft install fails to start

[thibaultcha]

Hi there,

Wanting to give fromscratch a try, I installed it via the snapcraft image (installed as such: https://snapcraft.io/docs/installing-snap-on-fedora):

$ sudo snap install fromscratch
...
$ fromscratch
$ echo $?
1
$ snap run fromscratch
$ echo $?
1

Running with strace:

$ strace fromscratch
...
statfs("/sys/fs/selinux", 0x7fff0fce46c0) = -1 ENOENT (No such file or directory)
statfs("/selinux", 0x7fff0fce46c0)      = -1 ENOENT (No such file or directory)
brk(NULL)                               = 0x55f2152d8000
brk(0x55f2152f9000)                     = 0x55f2152f9000
openat(AT_FDCWD, "/proc/filesystems", O_RDONLY|O_CLOEXEC) = 3
fstat(3, {st_mode=S_IFREG|0444, st_size=0, ...}) = 0
read(3, "nodev\tsysfs\nnodev\ttmpfs\nnodev\tbd"..., 1024) = 409
read(3, "", 1024)                       = 0
close(3)                                = 0
access("/etc/selinux/config", F_OK)     = 0
umask(000)                              = 002
openat(AT_FDCWD, ".", O_RDONLY|O_NOFOLLOW|O_CLOEXEC|O_PATH|O_DIRECTORY) = 3
fstat(3, {st_mode=S_IFDIR|0701, st_size=98304, ...}) = 0
chdir("/")                              = 0
getresuid([1000], [1000], [1000])       = 0
getresgid([1000], [1000], [1000])       = 0
geteuid()                               = 1000
write(2, "need to run as root or suid", 27need to run as root or suid) = 27
write(2, ": No such file or directory\n", 28: No such file or directory
) = 28
exit_group(1)                           = ?
+++ exited with 1 +++

And running as root:

 $ sudo snap run fromscratch

$ echo $?

For now, I reverted to installing the AppImage which worked fine, but I thought maybe you should know about the snap.

$ snap --version
snap    2.43.3-1.fc32
snapd   2.43.3-1.fc32
series  16
fedora  32
kernel  5.6.11-300.fc32.x86_64

Thanks!
